Custom RF Filters | Cavity, Coaxial & Strip Line Designs

Corry Micronics designs and manufactures custom RF filters engineered to meet the demanding frequency‑selection requirements of modern RF and microwave systems. Utilizing cavity, coaxial resonator, strip line, waveguide, and LC filter architectures, we deliver solutions optimized for your specific passband, rejection, power handling, and environmental requirements, from narrowband channelization to ultra‑wideband signal conditioning.

Whether you need a single prototype or production quantities of a proven design, our engineering team works directly with your RF systems engineers to define the optimal architecture, topology, and packaging for your application.

RF Filters

We design and manufacture custom RF filters for specialized architectures, each engineered for specific frequency, performance, and packaging requirements.

Cavity

High‑Q resonant cavity designs for applications requiring exceptional selectivity and low insertion loss. Ideal for communications infrastructure, radar front ends, and channelized receiver systems where adjacent‑channel rejection is critical.

Coaxial Bandpass

Compact, high‑performance coaxial bandpass filters delivering precision frequency selection with superior temperature stability. Available in standard and custom center‑frequency configurations from 2 MHz to 40 GHz.

Composite RF Filters

Planar strip line architectures for applications where size, weight, and integration matter. These filters offer excellent repeatability in production and are well‑suited for embedded RF subsystem designs in aerospace and defense platforms.

High Freq

High-frequency waveguide filters for 5G mmWave, V-band, and E-band systems operating above 60 GHz. < 1 dB insertion loss with 60 dB+ out-of-band rejection.

High Pass / Low Pass

Custom high-pass and low-pass filters for harmonic suppression and band separation. DC to 18 GHz operation with 80 dB+ rejection in connectorized, drop-in, or SMT packages.

LC

Discrete inductor‑capacitor filter designs for lower‑frequency RF applications and broadband requirements. LC architectures provide flexibility in passband shaping and are often the most cost‑effective solution below 1 GHz.

Strip Line

Surface Mount

Pick-and-place compatible SMT bandpass and duplexer filters for cellular infrastructure. Standard and custom configurations from 570 MHz to 2.7 GHz with low insertion loss.

RF Filter Applications

Corry Micronics RF filters are deployed across many mission‑critical systems.

Aerospace & Defense

Radar, EW, SIGINT, and tactical communications

Satellite & Space Communications

Uplink/downlink channelization and multiplexing

Test & Measurement

Signal conditioning for automated test equipment

Wireless infrastructure

Base station filtering, interference mitigation

Medical RF systems

Precision signal isolation for imaging and therapeutic devices

Custom RF filters

For applications requiring non‑standard specifications

Custom and COTS Availability

We maintain a selection of standard RF filter designs for common frequency bands and can deliver COTS solutions with short lead times. For applications requiring non‑standard specifications, our in‑house design and machining capabilities enable rapid development of fully custom RF filters, from initial simulation through qualification testing.

Every RF filter we build is custom‑tuned to your electrical and mechanical requirements.

Frequency coverage

2 MHz to 40 GHz+

Filter responses

Bandpass, high‑pass, low‑pass, band‑reject

Insertion loss

Typically < 1 dB (architecture‑dependent)

Rejection

60 dB+ out‑of‑band attenuation available

Power handling

From milliwatts to kilowatts

Temp stability

For demanding environmental extremes

Legacy Filter Replacement

If you're sourcing replacements for discontinued RF filters from Spectrum Control, Tusonix, or other legacy manufacturers, Corry Micronics provides form‑fit‑function replacement designs that eliminate the need for system‑level redesign. Our engineering team can cross‑reference your existing part numbers and deliver equivalent or improved electrical performance, including options for surface‑mount (SMT) filter configurations.

Legacy Single‑Line and Multi‑Line Filter Replacement

If you're qualifying a second source or replacing hard‑to‑find EMI/RFI filters or terminal blocks from Spectrum Control, Tusonix, or other legacy manufacturers, Corry Micronics supports the majority of legacy designs with form‑fit‑function replacements. Our engineering team can cross‑reference your part numbers and provide drop‑in equivalents with matched or enhanced electrical performance, all without requiring changes to your existing mechanical or PCB layout.
